I have self hosted wordpress *.tk blog. I have created an alexa account and submitted it there. Its almost two months but still it hadn't got an alexa rank, even after getting over a 300 backlinks. My previous *.wordpress.com blog has got a little more than a 100 backlinks, but it has a fair 5M alexa rank. Any ideas why?
They have a 3 month gross summation of traffic . Wait for another month and you will see an update. They also take 3 months to update any domain changes .
Any possible reason is if you have not used the 301 redirect properly .
